The engine P0213 OBD2 may also be caused by responsibilities earlier down the line. Such as, a dirty MAF sensor might be producing the car to overreact in its fuel-trim changes. As a result, oxygen sensors are likely to report fuel mix problems. Extreme air inflow can be a reason by a vacuum leak, a dirty/faulty sensor or, an finish gas recirculation valve not closing correctly. If the problem is not enough fuel, the criminal may be muted injectors or fuel filters, a weak fuel pump or a leaky fuel pressure regulator. Do not drive the car with the engine problem.
